A semi-nude Upton appears posing in a white furry parka (with half her breasts uncovered) and white bikini bottoms in the issue "Kate Upton Goes Polar Bear." The photos were reportedly shot in December and the SI cover marked the 50th Anniversary of the magazine's popular Swimsuit edition.

Upton posed for the famous Sports Illustrated Swimsuit cover in 2012 and her professional career spiked exponentially.

Last year, Upton nearly broke the internet when a video of her doing the 'cat daddy' dance went viral. The video, shot by photographer Terry Richardson showed Upton dancing to the famous tune. The swimwear model wore the same bikini she wore to grace the cover of Sports Illustrated in 2012.

The cover was reportedly leaked by Fashion Copious today and it was available on the magazine's website at the time of publishing.

TMZ however, posted the photo on its website and claimed that the photo shoot was taken in the middle of the frozen antartic tundra in December. Upton was also seen hugging a man dressed in an Oreo costume in the same photo shoot. "Kate braved the elements like a stud -- and it totally paid off," wrote TMZ.
